CNC Cabinet

Before start cutting some material i need to complete a CNC cabinet first, because it in my room and it close to my bed. So i need to protect dust , sound , dangerous stuff or endmill when it broken.

The cabinet it a bit fit to machine , actually i design it to have 5mm from Y Axis step motor to acrylic but in my design i use 4mm thickness and use some rubber between space of aluminum profile but i change my mind at last minute , then i order 6mm acrylic thickness and it make my space was now only 2mm.
